Explanation:
The changes that matter undergoes can be attributed to their properties.
Physical change is one of such.
- A physical change is one that alters the physical properties of matter especially its form and state.
- The physical properties of matter tells us everything about what a substance is when no change is occurring to its constituents.
- In most cases physical changes are usually reversible.
- Examples are boiling, melting, freezing, condensation, sublimation, magnetization of metals etc.
- Physical changes leads to the production of no new kinds of matter.
- They involve no mass change and requires little to no energy.

The process of separation of homologous chromosomes is during meiosis is referred to as disjunction. gametogenesis is production of gametes and it occurs in sex cells. disjunction occur during anaphase of meoisis I and in humans it results in separation of homologous chromosomes into two sets each containing 23 chromosomes. these chromosomes will eventually move to the opposite poles of the cell.

Explanation:
Answer:
When the plant inherits a recessive allele from both parents.
Explanation:
All organisms need both recessive alleles from the parents to receive that gene, or allele.
Answer:
Both leading and lagging strands
Explanation:
DNA replication is the enzyme of DNA replication that forms new DNA strands. However, the enzyme cannot start the process of synthesis of new DNA strands by itself but needs small primers. Primers are the small RNA sequences synthesized by RNA primase on both leading and lagging strands.
These primers are elongated by DNA polymerase by the addition of deoxyribonucleotides according to the sequence of the template strand. Since DNA replication on both lagging and leading strand is carried out by DNA polymerase, RNA primers are present on both lagging and leading strands.
